BUILDING CONSTRUCTION,

To all whom it may concern:

Be it known that I, GEORGE LESTER WIL- LIAMS, a citizen of the United States, residing in the city, county,'and State of New York, have invented an Improvement 1n vBuilding Constructions, of which the folof individual or preformed slabs of novel.

construction as will be described, and having transverse and longitudinal reenforcements individual to each slab, with the longitudinal reenforcements of adjacent slabs connected together between the same to form a continuous longitudinal reenforcement.

The individual slabs are preferably provided with end and side flanges, which cooperate to form the bottom walls of spaces between adjacent slabs, and which enable said spaces to be filled with plastic material without waste or danger of the plastic material dropping down between the slabs, which plastic material bonds with the individual slabs to form a monolithic floor or roof construction.

The invention further has for its object to provide novel means for anchoring the slabs and particularly the end slabs to the purlins which support the slabs, as will be described.

These and other features of this invention will be pointed out in the claims at the end plan of the Specification of Letters Patent. Pat t d J 27 1922' Application filed May 27, 1921.

Serial No. 473,206.

In the present instance, I have shown a sufficient portion of a floor or roof composed of a plurality of'individual preformed or precast reenforced slabs ato enable the invention to be understood. The slabs a are composed of plastic material, preferably gypsum, and are formed or cast in suitable molds, not shown, in which longitudinal metal reenforcing members and transverse metal reenforcing "members are properly positloned and secured in fixed relation to the mold before the gypsum or other plastic material 1s poured or cast to form the slab a. The mold is suitably shaped to provide the slab a with side flanges 12 and end flanges 13. The transverse reenforcing metal members are herein shown as three in number and comprise a member 14 located near the longitudinal center of the slab and at or near the bottom thereof, and members 15 located near the ends of the slab and upon the end flanges 13, being bonded with the latter.

The longitudinal reenforcement comprises as shown a plurality of metal rods or wires 16, which are of sufiicientlength to have their ends project through the end walls of the slab below the upper surface thereof and over the end members 15 in. close proximity to the latter, and preferably to extend under the center transverse reenforcing member 14, with which it cooperates to be placed under tension thereby and restrained against upward displacement.

The projecting ends of the longitudinal reenforc'ement are interlocked between the end walls of adjacent slabs and above the end flanges thereof, after said slabs have been placed in position in the building with adjacent ends of longitudinally adjacent slabs resting on a metal beam or other support 18, preferably with their end flanges 13 substantially in contact, in which position the end flanges resting on the beam 18 form the bottom wall of a space 19 between the end walls of the slab above said flanges. The end flanges 13 are made of suflicient width to permit the space 19 to be of sufficient widthv to enable an operator to quickly and easily interlock the longitudinal reen forcement of the adjacent slabs resting on the same support or beam 18.

The side flanges 12 are preferably made narrower than the end flanges, and cooperate with the flanges of transverse or laterally adjacent slabs to form a bottom wall for a space 20 between the side walls of said the spaces 20 to be filled with plastic material without waste of the latter and without damage which might be caused by the plastic material falling down between the slabs before the space was filled.

The space 19 between the end walls of the longitudinally adjacent slabs isfilled with gypsum or plastic material 22, which bonds with the Slabs and forms with the latter a monolithic floor or roof having a flush or continuous upper surface and having continuous longitudinal reenforcements and separate transverse reenforcements.

The longitudinal reenforcing members 16 of what may be termed the end-slabs a, are anchored at one end by metal members 30, see Figs. 1, 5 and 6, which are suitably c0nstructed to detachably engage the top flange 31 of the end purlin 32 and to be self supporting thereon and to be engaged by a transverse anchoring rod 33 with which the reenforcing members 16 are connected. The anchoring member 30 herein shown consists of a metal plate provided near its lower end with a slot 34, which e-rmits the plate to be slipped onto the top ange 31 of the purlin 32, and provided also with a finger or projection 134 at its upper end, which extends above the end flange 13 of the slab and has its rear surface engaged by the transverse anchoring rod 33. The slot 34: is made of suflicient length to have its upper'wall engage the upper surface of the flange 31 for a material length, to obtain a substantially long bearing for the anchoring member 30 to resist the strain placed upon it by thereenforcing members 16, and the slot 34 is .made of a width substantially equal to the thickness of the purlin flange 31 to enable the anchoring members tobe engaged with said flange before the end slab is placed in position, after the manner represented in Fig. 1.

he anchoring member 30 is preferably provided on its upper surface with a depression or socket 36 for the reception of the anchoring rod 33, so that the latter may be placed in position and be supported by the anchoring members 30 before the longitudinal reenforcing members 16 are connected with said rod, which may be effected by looping the ends ofthe members 16 around the rod 33 as represented in Figs. 1 and 6.

which can be done in a minimum time and with a minimum of labor by unskilled workmen. After the end slab has been laid in position and its longitudinal reenforcing members anchored as described, the projecting ends of the reenforcing members 16, the anchoring rod 33 and the anchoring member 30 may be covered with gypsum or the like, which forms a finishing member 37 indicated by full lines in Fig. 1 and by dotted which fills the spaces 19 and 20 bonds with the slabs a and forms a monolithic floor or roof.

Claims:

1. In a building construction, a reenforced slab comprising a' slab of plastic material provided with side flanges and with end flanges, transverse reenforcing members supported by said end flanges, an'intermediate trans-verse reenforcing member embedded in the slab substantially atthelongitudinal center of the slab and near the bottom thereof, and a longitudinal reenforcing member extended through said slab and inclined upwardly from the center transverse reenforcing member toward the ends of said slab and having its opposite ends projecting through and beyond the end walls ofthe slab above the end transverse reenforcing members.
